If a river's sediment load is 200 kg/m³ and the river has a flow rate of 10 m³/s, what is the total sediment transported in one hour? (2022)
720,000 kg
600,000 kg
1,200,000 kg
1,440,000 kg
Sediment transported = sediment load × flow rate × time = 200 kg/m³ × 10 m³/s × 3600 s = 720,000 kg.

Q
Q: If a river's sediment load is 200 kg/m³ and the river has a flow rate of 10 m³/s, what is the total sediment transported in one hour? (2022)
Solution: Sediment transported = sediment load × flow rate × time = 200 kg/m³ × 10 m³/s × 3600 s = 720,000 kg.
Steps: 7
Step 1: Identify the sediment load, which is given as 200 kg/m³.
Step 2: Identify the flow rate of the river, which is given as 10 m³/s.
Step 3: Determine the time period for which we want to calculate the sediment transported. Here, we want to find it for one hour, which is 3600 seconds.
Step 4: Use the formula for total sediment transported: Sediment transported = sediment load × flow rate × time.
Step 5: Substitute the values into the formula: Sediment transported = 200 kg/m³ × 10 m³/s × 3600 s.
Step 6: Calculate the result: 200 × 10 = 2000, then 2000 × 3600 = 720000.
Step 7: Conclude that the total sediment transported in one hour is 720,000 kg.
